RTG Supply Co - Wood Rot Repair Epoxy (Pint)

I have a deck stair made of one 12 x 3 piece of cedar (about 30 years old) that was rotting out from the inside on one end due to rain exposure. I mixed up half the solution and poured it into the top crack and blocked up the end with some stapled on cardboard. After about 20 minutes some of it really steamed (exothermic reaction) and set hard after 6 hours or so. Went back and drilled 1/4 inch holes into the areas that were soft under the hard upper original wood where the first batch didn't reach and filled in those with a syringe. That also steamed a bit after 20 minutes (probably a bit of moisture still inside the wood) but it set up hard. I then sanded the whole stair's upper surface since the material ran over the surface like a polyurethane. Cleaned it up really well. Now the stair is hard and does not give if you press on it. Excellent material for applications were it does not run out due to the viscosity being quite low. I have other applications where a 2 part clay type epoxy will be necessary, but this worked for my stair. Thanks!!!

When you need it you need it. Works as it should and does a good job but can only handle a smaller area than I needed. Seems like all these kinds of products have gotten very expensive and now come in smaller quantities. It works well and set up nicely, but I had to buy a sheet of plywood to keep the costs down. I would recommend it for tight space and small area of rot. Recommend, just measure the coverage you need to ensure you will have enough.

Reading the instructions, it says to use Acetone, or Denatured Alcohol to increase penetration, so I made the assumption that it would be a relatively thick epoxy.... This stuff is thin enough that in some of the worst areas, it penetrated all the way through the wood and dripped onto the ground. None of the lumber I was treating was bad all the way through, most of it was only 1/2 to 3/4" deep at the bad parts, and about 1 1/2" to 2" deep on the worst parts. The house was built in 1938 using local materials, the beams I'm repairing were sight cut 3 x 5 beams used as floor joists located in what was originally a laundry room that had flooded at least a couple times. It also had termite damage after the wood started to rot. It's now a bathroom, and I'm laying new floor down and will be tiling over it. This epoxy seems to be perfect for my usage, I just need the larger kit to finish the job.

This does a great job hardening rooted wood. Scrape out as much of the rotted wood as you can, mix this in a small cup and apply generously with a cheap paint brush. It soaks into the wood and dries very hard, stabilizing the rotted section so you can fill it in with a filler. Only complaint I have is it's very slow drying, couple of days.

Worked as specified. If you get a lot of heat from the mixture, you didn’t get the 2-1 correct. If you get white foam your area or wood was still wet.

I've used the product now in a number of different applications and it has not cured properly. I've mixed it to the milliliter, applied it under very controlled temperatures (65-70 degrees F) indoors with low humidity, applied heat and the wood has remained soft and pliable. I've read that old batches can lose their reactivity. I believe this may be an old batch of resin, hardener or both.

worked well, set up time fast but not too fast to work with. Not terribly smelly. Bought it twice

First I'd like to say how great this product is. I bought a house off a couple of octogenarians that was built in 1770. Needless to say it had been neglected for quite some time. My wife is not one to spend frivolously, especially when she's got a husband she can send to his death up ladders, scaffolding or traversing a roof with a rope. This epoxy can take a pretty roughly rotted board and make it solid again. There is a bit of learning curve to this, but once you get it you'll realize just how valuable it is when combined with some sister boards or some Bondo... you get the idea. With this house I only wish they sold it in 55 gallon drums! Now a bit about the company and they're fantastic customer service... I ordered the smallest size about a month ago, and it worked great, but I'm out. So earlier this week I ordered the quart size and was ready to get to work this weekend. Instead, I received some kind of tub paint! Mistakes happen and that's okay... I contacted the company Wednesday and they immediately sent out the right product! Needless to say, my wife was once again able to sacrifice me to this house this weekend! Thanks! 😊

Product is very hard to mix the right amount. This is not the fault of the product, but hard to estimate size of rot in the sill without ripping it completely out. DO NOT use if weather is to warm! Product bubbles if in direct sun. Took 3 coats to fully fill void. Definitely not for use where a clear, wood finish is required.

Product seems good, but seller not so good. Took longer than advertised to arrive. Took seller 5 days alone to ever create a shipping label, then shipping turned into 3 days longer than the original label implied.
